About:
Mpegdemux is a command-line utility designed to demultiplex MPEG1 and MPEG2 system streams. It extracts elementary streams, such as video (MPEG video) and audio (MPA), from program streams (VOB, MPEG-PS) and transport streams (TS, MTS). This allows users to separate audio and video tracks for further processing or playback on devices that do not support multiplexed streams.

Key Features:

Supports both MPEG1 and MPEG2 system streams
Extracts video and audio elementary streams to separate files
Command-line interface for scripting and automation
Handles Program Streams (PS) and Transport Streams (TS)

Use Cases:

Extracting AC3 or MP2 audio tracks from DVD VOB files
Separating video and audio streams for editing or transcoding
Analyzing the structure of MPEG system streams

Alternatives:

FFmpeg – FFmpeg is a much larger multimedia framework that can also demux MPEG streams and offers extensive transcoding capabilities.
ProjectX – ProjectX is a Java-based GUI tool for demuxing and repairing MPEG streams, often used for DVD processing.
